Can people with heart disease have an MRI?

Heart disease itself doesn't necessarily require an MRI, and it doesn't necessarily have much of an advantage. In general, the value of MRI in judging arrhythmia itself is not as great as that of electrocardiogram and electrophysiological examination, and the exploration of the gross structure of the heart is generally sufficient. MRI is only advantageous in cases where some ultrasound is not sufficient, such as aortic dissection.

For coronary heart disease, then coronary angiography is the first diagnosis, that is, multi-row (more than 64 rows) spiral CT can also be roughly done for coronary angiography. Therefore, if you look at heart disease, you may not need to do an MRI.

If the question is whether an MRI can be performed after a cardiac stent, then a cardiac stent can generally still undergo an MRI examination. Because the current bracket is generally made of non-magnetic or weak magnetic materials. Non-magnetic can generally accept magnetic resonance immediately (magnetic resonance field strength below 3t can be done immediately, generally even if the magnetic resonance field strength is not considered a very low magnetic field, in the past, some low field strength nuclear magnetic resonance can also provide good examination results).

If it is a stent made of weak magnetic material, then there is no problem with postponing the MRI examination for 6 weeks.

However, there is one situation in which magnetic resonance imaging must be prohibited, that is, patients who have a pacemaker (whether permanent or temporary) or ICD (implantable automatic defibrillator) because there are electronic components, which are very sensitive to magnetic fields.

In addition, magnetic resonance imaging is contraindicated in some patients who have cardiac hemodynamic monitoring devices such as cardiac flotation catheters or aortic counterflow pumps and ventricular assist devices.

For related content, I once wrote a blog "Safety Issues of Magnetic Resonance Examination after Implantation of Cardiovascular Devices", which was published on Sina Blog on March 13, 2010.

Generally, there are many people who do MRI examinations, and it may take the next day after the appointment, especially for large onesPublic tertiary hospitals, especially difficult to make an appointment, however, there are many private imaging centers now, no need to make an appointment, ** the effect is also better.

According to the old formula, because the metal can interfere with the applied magnetic field, the patient undergoes an MRI examination.

Before that, all metal objects must be removed from the body. Do not wear watches, metal necklaces, dentures, metal buttons, metal contraceptive rings.

and other magnetic items for MRI examination. Also, wear a pacemaker.

There are paramagnetic metal implants in the body.

Magnetic resonance imaging (MRI) is not available for metal clips, stents, plates, and screws. Perform epigastric (eg, liver, pancreas, kidneys, adrenal glands).

The MRI examination must be done on an empty stomach, but you can drink enough water before the examination, which is conducive to a clearer boundary between the stomach, liver and spleen.

Lesion found: MRI.

It is a new medical imaging technology that uses the principle of nuclear magnetic resonance to treat the brain, thyroid gland, liver, gallbladder, spleen, kidney, pancreas, adrenal glands, uterus, ovaries, and prostate.

and other solid organs, as well as the heart and large blood vessels, have excellent diagnostic functions. Compared to other adjunct tests.

MRI has the advantages of multiple imaging parameters, fast scanning speed, high tissue resolution and clearer images, which can help doctors "see" undetectable early lesions, and has become a powerful tool for early screening of tumors, heart diseases and cerebrovascular diseases.
